Fluidform Process

ECCO engineer their own 3D lasts which are designed to follow the foot's natural contours and support the footbed from all sides. These lasts are replicated into a flexible form via ECCO's Fluidform process which simultaneously generates a durable bond between the upper and sole of the shoe.

Comfort Insoles

ECCO shoes feature insoles that are designed for improved comfort and foot health. The foundation of ECCO's removable insoles is the ECCO Comfort Fibre System (ECFS), while the top layer is either constructed from leather, Poliyou®, or a combination of leather and textile. A 'pump' effect is activated when walking in ECCO shoes, which pushes air through tiny holes in the lining in order to promote air circulation underneath the foot.

Sustainable Leather

ECCO has been a member of the Leather Working Group since 2010. ECCO’s tanneries in Indonesia, the Netherlands, Thailand, and - most recently - China have again been awarded with a Gold Rating from The Leather Working Group.

ECCO Size Guide

How to find your size

Step 1

Stand on a level floor with your heel up against the wall or straight edge.

Step 2

Place a ruler or measuring tape on the floor under your foot or alongside it, with your heel at 0cm.

Step 3

Measure the length of your foot from your heel to the end of your longest toe (yes, even if it's your second toe).

Step 4

Measure both feet and go with the length of your longest foot if they are different. If you are in between sizes, we recommend going for the larger size.

Most Birkenstock styles are available in 'regular' or 'narrow' width.

Narrow width is suitable for narrow to slender feet.

Regular width is suitable for normal to wide feet.

If you already own a pair of Birkenstocks or are trying them on in store - check out the little foot symbol on the footbed. If the foot is coloured in, it's a narrow (N). If it's just an outline of a foot, it's a regular (R).
